Description
The project will consist of toxicity testing of 2 newly registered herbicides, imazamox and penoxsulam on Delta Smelt. Two bioassays will be performed to determine if the herbicides have any effects on the endocrine function (androgenic and estrogenic) of delta smelt during their life history. A preliminary will utilize the Japanese Medaka to determine endocrine effects of these low-toxicity chemicals and secondary endocrine tests with delta smelt will be applied based on the robustness of Medaka results. Water samples will be submitted to chemical analysis to determine concentrations of herbicides.
